1. Remove Airbox from Vehicle
2. Locate the side of the filter box facing the headlight assembly. In the lower left corner, remove the 3 center ribs on the outside of the box with Dremel.
3. Drill a 3" hole into airbox between the two remaining ribs.
4. Cut a piece out of the shop vac filter to fit area where the hole is and between the two ribs you didn't cut out.
5. Cut the Aluminum sheet to the same size as the shop vac filter and drill a 3" hole in the middle. Try to match the hole location in airbox.
6. Drill 4 pilot holes and attach to airbox using SS screws.

Recommendations:
1. Use material that won't rust.
2. Alternate material-Corragated metal (if you can find it)
3. Reason I chose shop vac filter? If it can keep water out of a shop vac motor, it will keep the bugs and water out of my K&N filter.

I was wondering if you were to somehow get this to mount to the mod and run it to the grille would it help more?
:yipi:

That looks like it would almost work with one of the vent slots between the bumper and the grille surround. Where did you find it?
I was trying to figure out how to rig up a scoop/tube from the opening where the tow hook is located.

Great mod Darcy.
In the Toyota world they've been doing an Airbox mod for years that might work well in conjunction with this.
They use a Marine "Deck Plate" and mount it over a corresponding size hole cut in the box (Deck plates can be purchased in sizes from 2" to 10"). This allows you to close up the hole during wet conditions where you may get to much water in (water crossings, bad rain storms, etc).
You can seal the edges of the deck plate with "Sensor Safe Silicone RTV" if you want a real leak free install.
A couple notes tho:
If you use RTV allow 24 hrs to cure and fumes filter out before starting the engine.
Only use sensor safe RTV, other types of RTV have a habit of screwing up the intake sensors when used and causing a CEL.
Deck plates can be bought from local Marine supply stores, Walmart, and places like Marine 1 or West Marine on the net.
I prefer plastic Deck Plates but metal ones are available also, they just cost more.
